You cannot have all the outputs active, in order to play 7.2.2 you need another amplifier, it should support it properly, in terms of sound volume, you can hear it somewhat well above 74+ and if you exceed it, it burns out, it burns out outputs, the protection does not have time to do its job, it blinks and does not turn on again, it needs repair, a Marantz or Yamaha that I had managed to survive before burning out outputs, unfortunately this one, either from ARC or a short circuit from the high volume, maybe distortion. As long as it plays and functions normally, it's fine somehow with low volumes. I hope I helped
